Specification of Letters Patent.

To all whom it may concern:

Be it known that I, CHAUNCEY C. CAR- PENTER, a citizen of the United States, residing at onconully, county of Okanogan, and State of Washington, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates 'My object is to provide cutters, knife or and smoother, by

plow, screen, and mulcher any crop may be cultivated and the which loosened earth crushed and left With a dust set forth hereinafter and disclosed in theacwhichplan view; Fig. 2, a side elevation; Fig. 3, a longitudinal section; and Figs. 4:, 5 an 6, cross sections on the lines 55 and 6-6, respectively.

e frame is composed of side bars or runners 1 which are connected by upper cross bars 2 and a rear smoother and mulcher have slot-and companying drawings, in

igure 1 1s a ners and are preferably provided with steel running or facing strips 5. The handles 6 are conveniently arranged so that the person shape, their lowerhorizontal cutting parts 0 being arranged so that they are below the lower edges of the bars or runners 1 and, consequently, adapted to penetrate the soil mg steelcross bars 12 connected to the runners 1. The bars 11 incline downwardly as to permit widening of the cultivator. the knife is in substantially the same plane as the lower faces of the cutting parts 10 so that it is adapted to run under the slice of the screen bars 11. e cam is connected to the bar 2 by any suitable olevis 19.

The screen stirs and breaks up the slice of earth and brings to the surface the coarser portions of the soil bars 12 and 3 to act more effectively in reducing the entire surof the soil as falls through the screen in front of them. The coarser portion of the slice of soil passes off of the upper rear end of the screen 11 and falls in front of the crushing and mulching bar 3 which completes the work of crushing, mulching and smoothing the sur- Patented Mar. 9, 1915.

The forwardedge 18 of i terminate at face, leaving it in the best possible condition to retain moisture.- The lower face of the mulch bar 3 being rearwardly and downwardly inclined,is adapted to exert a combined pressing and smoothing operation to effect the foregoing result.

Having thus described, my invention, I claim as new and desire to secure by ters Patent, is:

1. In a cultivator, the combination with a frame, of soil cutters carried thereby, an inclined screen over and through which the loosened soil is adapted to travel, the screen being located in the rear of the cutters, and a mulcher adapted to act on the earth.

2. In a cultivator, the combination with a frame, of soil cutters carried thereby, an inclined screen over and through which the what loosened soil is adapted to travel, the screen I being located in the rear of the cutters, and a mulch bar having an inclined face an located in the rear of the screen and adapted to act on the earth treated by said screen, i

3. In a cultivator, the combination with a frame, of soil cutters, a horizontal knife located in the rear of the cutters and adapted to raise the slice of earth cut by the cutters, an inclined open screen overand co ies of this patent may be obtained for Let V five cents each, by addressing the Washington, D. 0.

through which the soil is adapted to pass,

and a mulcher adapted to treat the soil which passes through the screen.-

l. In a cultivator, the combinationwith a frame, of soil cutters carried thereby, an

inclined screen composed of longitudinal. and crushing and mulching cross, located in therear ofsaid cutters, ahori Zontal knife located inadvance of,

cut 1 by the cutters and direct o it to said screen, and a mulch bar-located in the rear of the screen and adaptedto mulch the'soil barshe I screen in position to raise the slice of earth 3 crushing ,7 and mulching bars and located in the rear of the cutters,
